CHUTE.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed March 15, 1907. Serial No- 362,50O.

To all whom it may concern.-

. Be it known that I, GHAnLns H. SHUL'rz, a citizen of the United States, residing at St. Joseph, inthe county of Buchanan and State of Missouri, have invented a new and useful Chute, of which the following is a specification.

This invention relates to that class of chutes, which are placed in the walls of buildings and the like for directing material therethrough, and the principal object is to provide a very simple structure of a novel nature, which can be readily constructed, will constitute an effective chute, and is provided with means that will securely lock the closure in closed position so that it can only be opened from the inside.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of the chute. Fig. 2 is a vertical sectional view therethrough showing the same in place in a wall. Fig. 3 is a detail sectional view showing the closure in open position. Fig. 4 is a perspective view of the closure. Fig. 5 is a rear elevation of a portion of the casing frame. Fig. 6 is a detail sectional view through the casing on the line 66 of Fig. 2.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, an oblong casing is employed comprising opposite side walls 7 and a top and bottom 8. This casing is preferably formed of sheet metal, and has its front margin secured to the rearwardly extending flange 9 of a cast iron or other metallic frame 10. As shown in Fig. 2, the casing is arranged to be placed within a wall 11 so that the top and bottom thereof are at an inclination, the front frame 10 abutting against the outer face of the wall. Said frame is provided along its two outer sides and along the top bar with an outstanding bead 12, and the lower portion has spaced upstanding hooks 13 constituting bearings, as hereinafter set forth. A closure is employed, comprising a plate 14 preferably of cast iron that is arranged to fit within the head 12, and is provided along its lower margin with an outstanding rib 15 that detachably engages in the hooks 13 to form'a pivot connection between the closure and the casing.

The outer face of the plate is preferably reinforced by outstanding beads 16, and a strengthening rib 17, arranged transversely thereof, has its lower end 18 disposed at the lower edge of the plate, and arranged to abut against the frame between the hooks 13, thereby constituting a stop shoulder, which assists in maintaining the closure in line with the bottom of the casing when said-closure is swung to its outermost position, as indicated in dotted lines in Fig. 2. The closure plate 14 furthermore has spaced integral flanges 19 projecting from its rear face and disposed along its end margins.

To these flanges are riveted or otherwise secured side walls 20 of sheet metal so that they are relatively movable or in other words, cave a slight yielding movement. The rear ends of the side walls' are provided with cars 21, the terminals of which are preferably inturned, as illustrated at 22. The side walls 7 of the casing are provided contiguous to their inner ends with inner lugs or projections 23, and the outer frame 10 is also provided with lugs or projections 24.

When the closure plate is in its closed position, as indicated in Figs. 1 and 2, the cars 21 will be engaged beneath the lugs 23, and consequently will effectively maintain the closure in its closed position. When so located, the upper and end edges of the plate are arranged within the bead 12, and consequently said plate cannot be disengaged from the hooks 13. The closure is thus effectively secured in its closed position, and cannot be opened from the outside. It is only necessary, however, in order to release it, to press the cars 21 towards each other so that they will disengage from the lugs 23, whereupon the closure can be readily swung to open position, it being stopped by the shoulder 18 of the reinforcing rib 17 and by the lugs 24, so that it is in line with the bottom of the casing, and thus an effective chute is provided through which materials of all kinds can be readily passed.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent,

1. In a chute of the character set forth, the combination with a casing having an upright outer face and spaced upstanding hooks on its outer lower margins, of a swinging closure for the casing having a rib along its lower edge that is journaled in the hooks, the inner face of the closure when in closed position, abutting flat against the outer upright face of the casing.

2. In :1 chute of the character set forth, the combination with a casing, of a swinging closure pivotallymounted on the lower portion of the outer end of the casing, and a reinforcing rib located on the outer face of the closure, the lower end of said rib constituting a stop shoulder that abuts against the lower margin of the casing.

3. In a chute of the character set forth, the combination with a casing, of a swinging closure pivotally mounted on the lower portion of the outer end ofthe casing and having spaced marginal flanges projecting from its inner face, and side walls secured to the flanges and operating within the casing and having their inner edges located within the casing when the closure is in its outermost position.

4. In a chute of the character set forth, the combination with a casing having an outer frame provided with an outstanding bead along its outer portion, and an upstanding hook on its lower portion, of a swinging closure for the casing having its lower portion journaled in the hook and having its upper portion arranged to fit within the bead, and means for locking the closure in its closed position.

5. In a chute of the character set forth, the combination with a casing, of a swinging closure for the outer end of the casing, side walls carried by the closure and operating in the casing, said walls being capable of relative movement within the casing, and fixed projections carried by the interior of the casing and interlocking with the side walls when the closure covers the outer end of the casing, said Walls disengaging from the projections on their relative movement.

6. In a chute of the character set forth, the combination with a casing, of a swinging closure for the outer end of the casing, side walls carried by the swinging closure and operating in the casing, said side walls being capable of relative movement within the casing and having rearwardly extending ears at their inner ends, and spaced inner and outer fixed projections carried by each end wall of the casing, the inner projections interlocking with the ears of the side walls when the closure covers the outer end of the casing, said Walls disengaging from the inner lugs of the casing on their relative movement, and said ears abutting against the outer projections when the closure is in its outer position.

7. In a chute of the character set Iorth, the combination with a casing having an outer vertical frame and spaced upstanding hooks on its outer lower margins which open upwardly, of a swinging closure for the casing comprising a plate having a rounded rib along its lower edge that is journaled in the hooks and removable upwardly therefrom, the inner face of said plate, when in closed position, bearing fiat against the outer face of the casing.

8. In combination with the casing having a rearwardly extending flange to fit within an opening, and outstanding integral hooks constituting bearings, a swinging closure having a longitudinal integral rib along one edge to fit within the hooks, and a transverse rib provided on the closure and having one end adapted to form a stop shoulder.
